The materials (IGL sample series) consist of a lateritic soil, a dolomite, a limestone, an andesite,three different syenites and a gabbro, all of them sampled at different localities from Mexico. The resultsindicate that the IGL samples are physically homogeneous down to a sub-batch of 0.2 g with a 0.05significance level. Major and trace element provisional composition of these materials was obtained bywavelength-dispersive X-ray fluorescence spectrometry (WD-XRF). Statistical evaluation to verify forsufficient homogeneity was applied and sufficient chemical homogeneity at the 0.05 significance levelwas demonstrated. Calibration curves were constructed using the IGL samples in order to assess theirperformance as reference materials. Analyses of international reference materials (RGM-1, AGV-1, SDO-1, and Es-3) demonstrate the reliability of the IGL samples for calibration and intercalibration purposes.Provisional concentrations for 24 major and trace elements, as well as FeO and loss on ignition (LOI)values, are provided for all IGL reference materials. 2005 otro 1026-8774 https://www.redalyc.org/articulo.oa?id=57222307 en http://www.redalyc.org/revista.oa?id=572 Revista Mexicana de Ciencias Geológicas application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Ciencias Geológicas (México) Num.3 Vol.22 |
